Abstract

Don′t worry, B-happy: Hollow carbon spheres (HCSs) that were modified by doping with boron (B-HCSs) by using a CVD method showed high thermal stability compared with undoped HCSs. Pd was more-homogeneously dispersed on the surface of B-HCSs than on HCSs or on activated carbon. Pd/B-HCS is a selective, highly efficient, and recyclable catalyst for the solvent-free oxidation of alcohols.
